- Application filed August 15, 1918. Serial No. 78439314..

To all whom it may concern Be it known that we, KARL Vtinnnn, a subject of the German Emperor, residing at 12 Scharnhorststrasse, Dusseldorf, Germany, and Emu. MiiLLnn, a subject of the German Emperor, residing at 27 J ordanstrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Supports for Gun-Carrie e Wheels; and we do hereby declare the ollowin to be a full, clear, and exact description 0. the invention, such as will enable others skilled in the art to which it ai plpertains to make and use the same. carriage wheels, consisting of two or more parts, which are rigidly connected with the pivot which serves as an axis about which the gun can rotate.

' In the accompanying drawing, Figure 1 is a side elevation and Fig. 2 a plan view of the gun carriage and wheel supports. Fig. 3 is a vertical section and Fig. 4 a plan view oh a larger scale of the pivot and its attachments. Figs. 5 and 6 are sections of the wheel support through 'the lines 5-5 and 6--6 respectively of Fig. 2.

The device consists of two ormore wheel supports a, which are connected so as to be easily dismounted to a pivot 0 provided with four arms 6, b. The gun with its wheels is set on the wheel supports and connected to the pivot by means of two rods e secured by bolts (Z to the sides of the carriage.

On the wheel supports guides or racers f, and under the supports spiked attachments g, are riveted. The rods e secured by bolts tothe carriage are attached by two eyes 71. (Figs. 2 and i) to a pivot ring 2', which is mounted on the upper end of a bearing 7:, formed integral with the arms 6. The lower end of the hearing has a flange Z which fits in a circular recess formed in a central enlargement of the arms 6, which permits the arms to be closed like a. pair of scissors, so that it can be easily packed on an arti1- lery wagon (limber or the like). The wheel supports can also be packed on an artillery wagon and for that purpose can be easily detached from the arms of the pivot. The rods 6 with the eyes It can also be easily detached from the pivot ring 2? and during transport of the gun are raised and secured to special bearings m of the carriage.- The gun is accurately centered by the pivot and e invention relates to a support for gun the guides on the wheel supports. The whole arrangement enables the gun to be trained easily and quickly through a large angle, without the elevation of the carriage nd gun being affected to any important EX" tent.

spade should not enter the ground.

for defense against balloons, for which carriage support and pivotof the hind described is intended, are provided for this purpose with a hinged spade. l l hen the gun is aimed at targets on the ground, the hinged spade is placed in its operative posi tion and the carriage and wheels rest on the ground. if objects in the air are aimed at, the gun is placed on the wheel supports which are connected with the pivot; this provides a gun carriage with a central pivot for large training angles.

In order that the gun may be easily trained and the elevation of tie carriage trail but little changed, the hinged is raised, so that the trail only rests on a cover plate which is bent upward. This arrangement, allows the gun to be easily dis laced laterally since it has not to be raised y an amount sufficient to withdraw the spade from the ground. In order that the gun when fired should not be displaced rearward, since there is no spade the wheel supports are provided with the spiked attachments 9.

it the gun. is to have a horizontal traverse of 360 on its support, two additional wheel supports are provided, as shown by the chain dotted lines in Fig. 2, and are se cured to the arms of the pivot by bolts which are easily released. The edges of the wheel support are beveled (as shown in Fig. 6)

In order that the gun should be able to and are directed partly at right angles to their length anduayartly toward the axis of the pivot (Fig. The beveled edges at right angles to their ,length insure that the gun shall run on to the wheel supports in the axial direction. The edges in the direction of the axis of the pivot enable'the gun and wheels to be run on to the wheel support obliquely by moving the trail to one side or the other. The latter manner of running on to the wheel supports would be necessary in the firing position of the gun, if the wheel supports extending to a horizontal traverse of 45 on each side are to be used for larger training angles. In that case the gun when (he trail is shifted would run past the wheel supports, but remain connected to the rods e and the pivot ring 6, the wheel supports would then be turned through about 60 around the pivot and the gun would again run on. to the supports.

in this way it is possible with a wheel support which allows a traverse of 45 to each side to be able to train the gun through considerably larger angles.

An annular wheel support divided across a diameter, will also answer the same purpose, but can not he so easily transported and it is better, it" a wheel sup ort'is required for 360, to form it in our parts. .In practice it is however sufficient, if two wheel supports are connected by the pivot allowing the gun to be trained through 45 in each direction.

The advantage of these wheel supports is, that they are connected with the pivot by arms and do not form an undivided platform, so that the whole device can be easily and quickly packed and is considerably lighter than a single platform. A further advantage is that the wheels can be centered by the racers and the pivot. Since the wheel supports are provided-with spiked attach: ments, which are pressed into the earth by the whole weight of the gun, it is possible to tire without the spade anl to train the gun through the largest angles easily and quickly when aiming at 0b ects in the air.

Vi e claim as our invention: 1. In combination-with a gun carriage, a traverse platform having a plurality of wheel supports, a series of arms connecting said supports, pivoting means for said arms at the center of the. platform, and arms connected to said, said gun carriage.

.2. In combination with a gun carriage, a traverse platform having a plurality of wheel supports, spikes depending from said supports, a series of arms connecting said supports, pivoting means for said arms at the center of the platform, and arms connected to said pivoting means and also to said gun carriage. I

3. A traverse platform for gun carriages comprising a plurality of wheel supports, crossed arms detachably connecting said supports, a pivotal connection between saidarms at the center of the platform, and rodscarried by said gun carriage and designed to engage the pivot of said arms for centering said gun carriage on said platform, said pivotal connection permitting a relative rotary movement between the car riage and its supports.
